The effect of the oral iron chelator deferiprone on the liver damage induced by tamoxifen in female rats.

Tamoxifen (TAM) is a non-steroidal antiestrogen used in the treatment and prevention of hormone-dependent breast cancer. Tamoxifen therapy may be accompanied with hepatic injury and iron accumulation in this organ. The present study investigates the influence of the effective oral iron chelator, deferiprone (L1), in TAM-induced acute liver injury.

The effect of iron(III) on the activity of selenoenzymes and oxidative damage in the liver of rats. Interaction with natural antioxidants and deferiprone.

Iron is an essential element which, under certain conditions, can have prooxidant and cancerogenic effects. The effect of iron and iron chelators on the activity of selenoenzymes has been studied. Acute experiments in male Wistar rats demonstrated the prooxidant effect of iron on the selenoenzymes thioredoxin reductase (TrxR) and glutathione peroxidase (GPx).

Trace elements status in selenium-deficient rats--interaction with cadmium.

Although the metabolic and toxicological interactions between essential element selenium (Se) and toxic element cadmium (Cd) have been reported for a long time, the experimental studies explored mostly acute, high-dose interactions. Limited data are available regarding the effects of Se-deficiency on toxicokinetics of cadmium, as well as on the levels of key trace elements--copper, zinc, and iron. In the present study, male and female Wistar weanling rats (n = 40/41) were fed either Se-deficient or Se-adequate diet (<0.
